To all whom it may concern:

Be it known that l, Jo N. LEAUII, a citizen ol the ied States, ding at Melrose, in the county of liliddles 1i and State of Massachusetts, have in'vc ed new and useful improvements in Blot-oehicles, of which the lOllOl'f'lPg is a syeciiication.

This invention relates to iinprovcmcnts in motor vehicles and particularly to improve ments in steam motor vehicles of the type in which the engine is supported on the rear as: e, and the objectis first, to provide a motor vehicle ol this class in --.rhich the engine shall be accessible r the purpose of making repairs and adjustments and inspecting the same. Second, to provide a motor vehicle in which the rear axle and its casing may in a few moments be bodily removed the vehicle. Third, to provide an engine casing which shall thoroughly protect tire engine from dust and mud and yet be easily and quickly opened to expose the working parts of the engine. Fourth, to givea greater road clearance beneath the e; no, tnis latter ob ject being attained by mounting the engine crank shaft above the axle and, fifth, to pro-- vide means for adjusting the driving gears with relation to each other.

Still other objects and advantages will appear hereinafter.

The invention consists in the combination and arrangement of parts set forth in the tollov ing specification and particularly pointed out in the appended claims.

Referring to the Clllf. igsz Figure 1 is a side elevation of a motor vehicle embodying my invention. Fig. 2 is an. enlarged detail plan of the engine and a portion. of the frame, the axle being partly broken away to save space in the drafting. Fig. 3 is an enlarged detail re r elevation, partly broken away and shown partly in section. Fig. 4.- is a detail sectional elevation taken on line Fig. 3, looking tov. ard the right. Fig. 5 is an en larged detail plan section taken on line 5 oi Fi '6 is a sectional elevation taken on line (3-6 of Fig. 3, looking to; ard the right, partly broken away to save space. Fig. 7 is a detail plan of one of the upper spring seats shoving its pivotal connection with the body of the vehicle. l 8 is a sectional elevation, partly broken a ay, taken on line 8-8 oi Fi 3, looking toviard the right. Fig. 9 is a sectional elevation taken on line 9 9 of Fig. 6, looking tovrard the left.

10 is an enlarged detail sectional elevatior talten on line 10-1G oi i :e numerals refer to like i ts throughout rue several vices t the dram ings.

In the drawings, .10 is the body of the motor vehicle supported on front Wheels 11 and rear driving wheels 1 'llwo rear spri s 13 are pivoted at 141 on a .e frame 15 oi the body 10. The springs 13 are rigidly :nred to spring 16 each of which is d in wo members 17 and 18 pivotally conn-cted to each other at 19. Screws 20 having screu threaded engagement nith the members 17 and passing through the membore 18 secure said members together. The spring seat 16 surrounds a tubular axle 21 and is journaled thereon, said. axle being provided with annular 22 located on each side of the spring seats. T1 50 radius or distance rods 23 pivotally connected at 24 to the spring seats 16 are also pivotally connected at 25 to brackets 26 fast to the frame 15. iigidly secured to the parts of the tubular axle 21 is a differential casing 37, there being two struts 28 "which serve to strengthen the axle 21. A second casing 29 is formed in two members 30, 30 which are secured to each other by means of sceris 31 and secured to the casing 2'7 by means of screws 82.

An engine casing 83 which inoloses an enginc 3% which may be of any suitable con struction comprises a cylinder casing 35, a member 36 secured to an engine frame 37 by means of secrets 38, to members 39, 39 pivoted at 40, to the member 36, and two members 41, 41 pivoted at 42, e2 to the members 39, respectively. The members 41, 41 are provided, respectively, i'vith lugs 43, 48, the lugs of one of said members being provided respectively, r. ith slots 4-4 and the lugs of the other of said members being provided, respectively, with screw-threaded holes 45 in which located L-shaped screws 46 extending through the slots 44;, respectively, and sering to attach the adjacent edges of said members together. By rotating the screws 46 90 until their handles l7 are located in alinement with the slots 44, respectively, the two members 411. may be disconnected from each other by drawing them apart, the handles 4L6 passing through the slots 44. The engine 34 comprises a crank shaft 48 journaled in crank shaft bearings 49 which are secured to rods 50 contrio able type of boiler as 61 vhich may stituting a part of the engine frame 37. The crank shaft bearings 49 are pivotally supported on a bolt 51 which extends through said bearings and through the casing 27. Studs 52 passing through the casing 27 and having screw-threaded engagement therewith are provided 'ith shoulders 53 on which the crank shaft bearings 49 rest. Nuts 54 having screw-threaded engagement with said studs secure said studs against rotation in the casing 27. Nuts 55 having SCIGT-tl'ltfiitded engagement with the upper ends of the studs 52 bear against washers 56 and serve to rigidly secure said studs to the crank shaft bearings 49.

A spur gear 57 fast to the crank shaft 48 meshes into a spur gear 58 which may be connected to a driving or live axle 59 by means of the customary differential gearing, said live axle being in practice formed in tr. 0 parts individually connected. to the driving wheels 12. By loosening the nuts 54 and 55, the studs 52 may be rotated to adjust the gear 57 toward or av. ay from the gear 58 in order that said gears may be properly meshed.

A steam pipe 60 rigidly connected to the engine 34 is flexibly connected to any suitbe mounted on the frame 15 of the vehicle, said steam pipe extending through a depending support 62. The support 62 comprises a ball and socket joint which consists of a socket 63 and a ball 64, said socket being formed in we parts connected by bolts 65. An arm 66 fast to the ball 64 is pivotally and slidably connected to the steam pipe 60, while an arm 67 formed integral with the socket 63 is pivotally connected to a plate 68 fast to a cross piece 69 constituting a part of the frame 15, the pivotal pin 70 extending transversely of the vehicle. The support 62 constitutes a universal connection between the front end of the engine and the frame 15 so that as the body 10 moves up and down on the springs 13 and the frame 1.5 moves toward and away from the axle 21 the engine 34 and its casing 33 together with the axle 21 st ing about the axis of said axle and said axle sv. ivels in the spring seats 16. The pivot 70 and ball and socket 64 and 63 are arranged to permit perfect freedom of movement of the body 10 with relation to the engine and its casing.

The body 10 of the vehicle may be suitably constructed so that the engine and its casing may be gotten at easily. In the present embodiment of my invention, I have shown the body 10 provided with a tailboard 71 hinged at 72 to a cover 73, said cover being hinged at 74 so that said tailboard and cover may be folded up out of the way. When it is desired to get at any of the parts of the engine to adjust or repair them, the casing 33 may be unfastened and opened into the position shown in dotted lines in Fig. 9, thus leaving all of the important workingparts of the engine entirely free for inspection. It will be seen that the member 36 of the casing 33 constitutes a pan adapted to receivethe excess oil which may drop from the engine 34. If at any time it becomes necessary or desirable to remove the rear axle of the engine bodily from the vehicle, this is done by removing the screws 20 and opening the spring seats 16 by rocking the members 18 on their pivots 19 and after the steam pipe 60 has been disconnected the axle 21, the wheels 12, and the entire engine and its casing-may then be bodily withdrawn from the vehicle for such repairs as may be necessary.
